AGP upgrade assistant - from 8.2.2 to 8.3.0-rc1

Currently stuck at Gradle 8.2.2 and cannot upgrade further. Using AGP upgrade assistant with latest otter 2 android ide.

The error is

No such property: signingConfig for class: com.android.build.gradle.internal.core.dsl.impl.ApplicationVariantDslInfoImpl

Despite adding signingConfigs in 8.2.2 build.gradle (compiles with no issues)

android { signingConfigs { debug { // ... keys } } buildTypes { debug { // USE THIS SYNTAX signingConfig signingConfigs.debug } } }

How to get this resolved? Objective is to move 8.5.2 for 16kb page alignment
